After surgical repair of a superior sinus venosus defect and anomalous pulmonary venous drainage, a 4-year-old girl was found to have a long-segment stenosis of the superior vena cava (SVC) as it entered the right atrium, anterior to the right upper pulmonary venous baffle. A 3-dimensional (3D) printed model created from the magnetic resonance imaging (MRI) data more clearly demonstrated the relationship of the SVC stenosis to the right upper pulmonary vein baffle, giving operators the confidence to proceed with balloon angioplasty of the SVC.
